I am using the lastest dll for drawer the drawer is working fine but when i add the xamarin forms Maps Then   rotation makes the application to crash start again i dont know what happen with the drawer as the same error of disposed objects are coming

[Selva Kumar Veerakrishnan]

Hi jahanzaib zahid,

We would like to know more information to reproduce this issue. Is Xamarin forms maps has been used inside the SfNavigationDrawer? or by adding the Xamarin forms maps package to the project makes the Object disposed error. Also let us know whether you have used Xamarin.GoogleMaps NuGet or Syncfusion.Xamarin.Maps NuGet package

An issue reproducing sample with replication steps for the will be more useful for us to provide better solution on this.

Yes i am using the Xamarin.Forms.Maps from nuget and the problem is that it makes the Xamarin forms updated to latest version as well  which result an error of object disposed while rotating the application  I am not using the Syncfusion Map because i need a native look and feel of maps and  your map has not any feature like  Xamarin.Forms.Maps   I  cannot complete my application because of this issue Hoping to hear you soon 

[jahanzaib zahid]

I am facing this issue again and again and cannot even find  a method to solve i dont know why your controls is not compatible with the latest version of xamarin forms

[Selva Kumar Veerakrishnan]

Hi jahanzaib zahid,

Query: I am not using the Syncfusion Map because i need a native look and feel of maps

Can we know your feature list that need to be implement as like Xamarin.Forms Maps so that we can analyse feasibility to provide this support if possible, and will implement in any of our volume releases.

Query: Object disposed error when using NavigationDrawer with Latest Xamarin.Forms.Maps”

We could not reproduce the issue “Crash when rotating NavigationDrawer when Xamarin.Forms.maps is added to it” We have prepared a sample for your reference and recorded a video for the output, please download the same from the link given below.
